That's good news that you know that she can go on. Being confident that you can do this is one of the keys - you can do this hun

If your DD is vomitting after the bottle, she is not still hungry. It is most likely that she wants to suck and the behaviour looks like hunger (it's confusing isn't it!!). You could try her on the breast once she's had some EBM or otherwise try and settle her by holding her or wearing her in a sling. I am reluctant to suggest a dummy until you have breastfeeding going well, but maybe she could suck on your finger for a few minutes after the bottle if she wants to suck.

You are making progress hun and you will get there. Perhaps today you might like to hold her skin to skin when she's calm and not due for a feed and just see what happens. Often when there is no pressure to feed babies will attach well. GL.
